CROSS REFERENCE TO RELATED APPLICATION

This application claims priority to U.S. Provisional Application No. 62/554,468, filed on Sep. 5, 2017, herein incorporated by reference in its entirety.

BACKGROUND

Noise is typically defined as unpleasant and unwanted sound. High noise levels worsen patient and staff outcomes in hospitals, hinder teaching and learning in schools, negatively impact productivity in offices, and disrupt living environments in homes, apartments, and condominiums. With flooring, one of the most abundant finishes in the built environment, the opportunity to positively influence the acoustical performance of a space is great. Different commercial floor coverings such as wood, ceramic, wood, resilient/vinyl, carpet and textile composite flooring control sound differently. Harder materials such as ceramic, wood, and resilient/vinyl absorb little or no sound and have greater potential to transmit sound, contributing to a noisier environment. Softer materials such as carpet and textile composite flooring absorb significantly more sound and transmit less sound, contributing to a quieter environment.

Tests exist that can measure the acoustic properties of interior surfaces and finishes. Such tests involve measuring the noise levels produced during the various test procedures, but the test results are typically reported only numerically as a classification or result. The classification or result is simply a number that means nothing beyond any scale that may apply to the classification or result. The classification or result does not communicate any information related to the way humans perceive sound. Consequently, it can be difficult to effectively communicate the test results to homeowners, developers, purchasers, contractors, manufacturers, and other stakeholders, and a primary goal of the tests—to assist in building design and construction—is therefore not met. These and other shortcomings are addressed by the present disclosure.

Any suitable computer-readable storage medium may be utilized including hard disks, CD-ROMs, optical storage devices, or magnetic storage devices.

Embodiments of the methods and systems are described below with reference to block diagrams and flowchart illustrations of methods, systems, apparatuses and computer program products. It will be understood that each block of the block diagrams and flowchart illustrations, and combinations of blocks in the block diagrams and flowchart illustrations, respectively, can be implemented by computer program instructions. These computer program instructions may be loaded onto a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions which execute on the computer or other programmable data processing apparatus create a means for implementing the functions specified in the flowchart block or blocks.

These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including computer-readable instructions for implementing the function specified in the flowchart block or blocks.

As will be described in greater detail herein, systems and methods provided can provide a tool to compare acoustic performance of one or more products (e.g., flooring materials) using audio and/or video information that represents real-life performance. The audio and/or video information can represent a range of parameters allowing for comparison of varying flooring materials. This includes the ability to compare the audible difference of products and/or assemblies that have the same or similar numerical ratings.

The tool can ensure that a user is able to filter and compare results based on key product parameters (e.g., a type and/or material of flooring; an amount and/or type of padding; etc.) and building assembly parameters (e.g., construction material of a building; dimensions of a building/room; etc.). This allows the user to actually hear an accurate representation of the sound performance of multiple construction configurations during the design phase of a project.

In an aspect, the tool can comprise an interface (such as a web page) from which the user can select a floor assembly, a ceiling assembly, and/or a product configuration. Because a floor assembly, a ceiling assembly, and/or a product configuration with a given numerical classification or result may absorb and/or reflect sound differently based on product configuration, installation environment, and the like, the user selections result in a query to a media database where resulting audio file(s) can then be rendered for the user to hear the actual result for each combination, rather than merely relying on the given numerical classification or result. The disclosed tool enables comparison of acoustic performance of building materials in an easy to understand, intuitive format. For example, a user may select a floor assembly, a ceiling assembly, and/or a product configuration based on descriptive terms, rather than numerical ratings, of each (e.g., “hardwood flooring” with “2 inches of foam padding” in a “large room” with “gypsum board walls”). Acoustic performance of building materials can be compared by anyone who can operate and hear the tool, not just an acoustics specialist.

The typical frequency range for normal human hearing is 100-10,000 Hz. The human voice falls within the low-frequency end of the spectrum, at around 100-3,500 Hz. Building noises such as those emanating from elevators, HVAC systems and mechanical systems fall near the 1,000 Hz range. Loud noises such as alarms and bells are in the high-frequency end, up to 10,000 Hz. An airborne noise test relates to a surface's ability to absorb these and other airborne sounds which contribute to ambient (background) noise. The airborne noise test, ASTM C423-02a, measures a surface's ability to absorb these and other airborne sounds which contribute to ambient (background) noise. A floor covering sample is typically tested in a reverberation room. The test measures the product's absorption of sound at 15 different frequencies ranging from 100 Hz to 10,000 Hz. All of these frequencies fall within the range of what a normal human ear can hear. A floor covering's measure of effectiveness in absorbing airborne sound is expressed as a Noise Reduction Coefficient (NRC). The greater the absorption, the higher the NRC number. A surface that completely eliminates sound has an NRC of 1.0. Hard surfaces such as rubber and vinyl typically have NRCs of about 0.0-0.015, meaning they absorb little to no airborne sound. Commercial carpets used in hospitals, schools and offices have NRCs typically ranging between 0.15 and 0.2, meaning they absorb about 15-20 percent of airborne sound. A textile composite flooring's NRC is about 0.30, meaning 30 percent sound absorption.

A structure-borne noise test relates to a surface's ability to absorb impact noises, reducing surface noise generation and impact sound transmission into a space below. The structure-borne noise test most used for flooring, ASTM E492-09, studies a material's ability to reduce impact sound transmission into a space below. Footsteps and objects dropping on the floor are examples of impact noises. The structure-borne noise test is performed using a tapping machine in which five hammers strike the floor 10 times per second. Sound pressure in 16 frequency bands is measured in a reverberation room below the floor being tested. The measure is expressed as a whole number, Impact Insulation Class (IIC)(derived from ASTM E989, incorporated herein by reference). The higher the numerical rating, the greater the sound insulation. ASTM E989 is merely an example of a test that can be applied to the disclosed methods and systems. Other tests are contemplated, including, but not limited to, IIC and delta IIC (ASTM E492-09, ASTM E989-06, ASTM E2179-03, ISO 10140-3), STC (ASTM E90-09, ASTM E413-16, ISO 10140-2), and/or Noise Reduction/Absorption (ASTM C423-17, ISO 354, ISO 11654).

FIG. 1A illustrates a system 100 configured for a structure-borne noise test. The structure-borne noise test can be performed using a tapping machine 102 in which one or more hammers 104 strike a floor 106 a predetermined number of times per second (e.g., 10 times per second). The tapping machine 102 is positioned on the floor 106 in a space 108. The space 108 can be a room of a building. The space 108 can be positioned to be above (e.g., on top of) another space 110. A floor/ceiling assembly 120 can separate the space 108 and the space 110. The floor/ceiling assembly 120 can comprise one or more materials that separate the space 108 and the space 110. The floor/ceiling assembly 120 can vary widely amongst structures. FIG. 1B provides an example floor/ceiling assembly 120. The floor/ceiling assembly 120 can comprise, for example, a floor covering 122, a padding 124, an underlayment 126, a subfloor 128, a structural member 130, a ceiling support 132, a ceiling 134, an insulation member 136, combinations thereof, and the like. The floor covering 122 can be, for example, a carpet covering, a resilient/vinyl covering, a hardwood covering, an engineered hardwood covering, a tile covering, and the like. The underlayment 126 can comprise, for example, rebond, frothed foam, waffle rubber, urethane foam, bonded urethane, flat rubber, fiber cushion, slab rubber, fiber, cork, and the like. The subfloor 128 can comprise, for example, hardboard, particle board, oriented strand board (OSB), plywood, concrete, and the like. The structural member 130 can comprise, for example, joists, trusses, a concrete slab, and the like. The ceiling support 132 can comprise furring channels. The ceiling 134 can comprise drywall, plaster, tile, and the like. The insulation member 136 can comprise, for example, fiberglass, mineral wool, plastic fibers, natural fibers, foam board, foam, cellulose, and the like. The floor/ceiling assembly 120 illustrated in FIG. 1B is merely an example floor/ceiling assembly 120. Many variations exist that vary not only the types of materials used but also which materials are used. For example, some floor/ceiling assemblies may lack a floor covering and/or a ceiling, or may lack an insulation member, and the like. In an aspect, a floor/ceiling assembly can comprise solely a structural member, such as a concrete slab.

Returning to FIG. 1A, the floor 106 can comprise any of the floor covering 122, the padding 124, the underlayment 126, the subfloor 128, the insulation member 136, the structural member 130, combinations thereof, and the like. As the hammers 104 of the tapping machine 102 strike the floor 106, sound travels through the floor 106 of the space 108 and a ceiling 112 of the space 110. The ceiling 112 can comprise the structural member 130, the ceiling support 132, the ceiling 134, the insulation member 136, combinations thereof, and the like. Sound pressure 114 in one or more frequency bands (e.g., 16) can be measured in the space 110 using a microphone 116 coupled to a computing device 118. A measurement can be expressed as a whole number numerical rating, Impact Insulation Class (IIC). The higher the IIC, the greater the sound insulation. ICC ratings vary, depending on materials and construction. For example, IICs for VCT typically range from 15 to 20, rubber IICs range from 15 to 30, carpet IICs range from 35 to 50, and the IIC for textile composite flooring is 64. The algorithm for converting sound pressure to a classification or result can be found in ASTM E492-09 & ASTM E989-06, incorporated herein by reference in its entirety.

The system 100 can be further configured to record video and/or audio. For example, the system 100 can record the sound pressure 114 that results from the hammers 104 of the tapping machine 102 striking the floor 106 causing sound to travel through the floor/ceiling assembly 120 and into the space 110. In an aspect, the floor/ceiling assembly 120 (including for example, the floor 106 and/or the ceiling 112) can be made of many different materials, or the same material. A plurality of combinations of materials for the floor/ceiling assembly 120 can be installed. For each of the plurality of combinations, the microphone 116 can record the resultant sound pressure 114. The computing device 118 can be configured to store the recording as a media file (either uncompressed or compressed (lossy or lossless)).

In various embodiments, the media file may include electronic representations of video, audio, text and/or graphics, which may include but is not limited to electronic representations of video, audio, or other multimedia, (e.g., video file) which may include but is not limited to data files adhering to MPEG2, MPEG, MPEG4 UHD, HDR, 4k, Adobe® Flash® Video (.FLV) format or some other video file format whether such format is presently known or developed in the future. In various embodiments, the media files described herein may include electronic representations of music, spoken words, or other audio, (e.g., sound file). The sound file can be, for example, in an uncompressed audio formats, such as WAV, AIFF, AU or raw header-less PCM. The sound file can be, for example, in a format with lossless compression, such as FLAC, Monkey's Audio (filename extension .ape), WavPack (filename extension .wv), TTA, ATRAC Advanced Lossless, ALAC (filename extension .m4a), MPEG-4 SLS, MPEG-4 ALS, MPEG-4 DST, Windows Media Audio Lossless (WMA Lossless), and Shorten (SHN). The sound file can be, for example, in a format with lossy compression, such as Opus, MP3, Vorbis, Musepack, AAC, ATRAC and Windows Media Audio Lossy (WMA lossy).

The computing device 118 can store (e.g., in a database) the media files along with the associated combination of flooring and/or ceiling materials used when generating a respective media file. The database of the computing device 118 can be transferred to another computing device (e.g., a server) for use with the disclosed tool.

FIG. 2 and FIG. 3 are block diagrams depicting non-limiting examples of a server 202 and a client 206 connected through a network 204 according to an aspect. The server 202 can comprise one or multiple computers configured to operate an acoustic engine 302. The client 206 can comprise one or multiple computers configured to operate an interface 304 such as, for example, a laptop computer, a smartphone, a desktop computer, and the like. Multiple clients 206 can connect to the server 202 through a network 204 such as, for example, the Internet. A user on a client 206 may connect to the acoustic engine 302 with the interface 304.

The acoustic engine 302 can be configured to receive one or more queries related to a selection of one or more materials of a floor/ceiling assembly (for example, one or more of a flooring material or a ceiling material). The acoustic engine 302 can determine one or more media files associated with the query and make the one or more media files available for output by the client 206. FIG. 4 is a block diagram depicting an exemplary view of the acoustic engine 302 according to an aspect. The acoustic engine 302 can provide search results responsive to a user-defined search. The acoustic engine 302 can comprise one or more of, a query module 402, a search engine index 404, and a media file module 406. The search engine index 404 can analyze metadata associated with one or more media files to determine how to index the one or more media files. The metadata can comprise, for example, a type of material of a floor/ceiling assembly, a timestamp, a location, a building type, a classification or result (e.g., IIC classification), a decibel rating, a combination thereof, and the like. The metadata about the one or more media files can be stored in the search engine index 404 for use in queries by the query module 402.

The query module 402 can be configured to perform one or more types of searches. In an aspect, the query module 402 can be configured to perform a keyword search. A keyword search is a type of search that looks for matching electronic documents (one or more media files) that contain one or more words specified by a user. In an aspect, search statements provided to the query module 402 can be constrained to a finite listing of possible search terms. For example, the query module 402 can be constrained to only execute a search for materials found in the search engine index 404. In an aspect, the query module 402 can be configured to search based on a classification or result. For example, a user can specify a classification or result and one or more media files associated with materials of a floor/ceiling assembly that resulted in the classification or result (or a better classification or result) can be determined.

The search engine index 404 can be a database listing comprising, for example, electronic documents, electronic document metadata, and the like, referred to herein as search results. Searching the search engine index 404 can utilize the metadata. For example, searching the search engine index 404 by metadata can comprise performing a Boolean search. For example, metadata associated with a first media may indicate the first media file is indicative of sound for a first flooring type, a first building material, and a first room size. The user-defined search may indicate the first flooring type, the first building material, and a second room size. In this case, the first media file would not be part of the search results, since the room size associated with the first media file does not match the room size indicated by the user-defined search.

The media file module 406 can be configured to process one or more media files identified by the query module 402 as responsive to a search. In an aspect, the media file module 406 can cause the one or more media files to stream, download, or otherwise cause to be rendered by a client 206. The media file module 406 can be configured to transcode the one or more media files from one format to another, based on playback requirements imposed by the client 206. In yet another aspect, the media file module 406 can be configured to mix, overlay, normalize, or otherwise process the one or more media files. For example, the media file module 406 can be configured to adjust loudness of the one or more media files. In an aspect, the acoustic engine 302 can receive a volume setting for the client 206. Based on the volume setting, the media file module 406 can manipulate the one or more media files to ensure that the one or more media files, when rendered by the client 206, are played at an appropriate loudness to ensure that the audio playback is representative of the originally recorded sound. For example, a device playing the media file can play a calibrated sound. A microphone coupled or built in to the device can be used to receive the output and the software on the device can adjust an equalizer and/or volume to ensure the calibrated sound is played according to a known performance level.

In another aspect, upon executing a query and failing to identify a match based on the test data or the media files characteristics. These can be used to group products with similar design or sound performance at all frequencies. The disclosed methods and systems can then associate the group to the closest match to the query for playback. For example, if a floor covering ‘A’ was tested and had a recorded media file and floor covering ‘A’ used the same material and thickness as floor covering ‘B’ but had different dimensions and had similar results across all tested frequencies (e.g., 50 Hz to 10,000 Hz), the system can utilize the media file for product ‘A’ when product ‘B’ was in the executed query.

In an aspect, the disclosed methods and systems can perform sound performance audio mapping and prediction. A database can be created that comprises one or more (e.g., all) testing parameters, resulting measurements, summarized test results, and associated media file(s). Examples of testing parameters include, but are not limited to, test conducted, material(s) used in floor/ceiling assembly, combination(s) of materials used in floor/ceiling assembly Examples of resulting measurements include, but are not limited to, dB, absorption, and the like, across the tested frequencies (Hz). Examples of summarized test results include, but are not limited to, IIC, STC, and the like. One or more of each of the aforementioned testing parameters, each of the resulting measurements, and/or each of the summarized test results may be associated with a metadata for a given media file.

The database can be analyzed to create a prediction model that can predict the resulting measurements and summarized test result for a combination of test parameters that may not have been tested. The predictive model can be created using one or more algorithms (e.g., regression, k-nearest neighbors, random forest, decision tree learning, etc.). The predictive model can be updated as new test results are added to the database, either manually or automatically.

Accordingly, if a user selects a unique combination of test parameters where an actual test has not been conducted (and therefore no associated media file exists), the system can provide the query to the prediction model to predict the resulting measurements and summarized test results for the requested parameters and present them to the user. The predicted measurements can then be compared to the test measurements in the database of existing tests. If the predicted test measurements are within a defined range across all the test measurements of an existing test (for instance +/−3 dB for each frequency), the sound/media file of the matching test will be presented to the user as a representation of what the requested parameters should sound like in a real test.

FIG. 5A is a diagram depicting an example of a web browser screen 500 showing search results generated based on a user defined query. The web browser screen 500 can comprise one or more search boxes associated with one or more materials of a floor/ceiling assembly. For example, the web browser screen 500 can comprise a classification or result search box 502, a floor covering search box 504, an underlayment search box 506, a subfloor search box 508, a structural member search box 510, a ceiling search box 512, a search button 514, a result indicator 516, and media controls 518. Other search boxes are contemplated for any material and/or layer of a floor/ceiling assembly. A user inputs a search term in at least one of, the classification or result search box 502, the floor covering search box 504, the underlayment search box 506, the subfloor search box 508, the structural member search box 510, the ceiling search box 512, and initiates a search by clicking on the search button 514. In an aspect, the classification or result search box 502, the floor covering search box 504, the underlayment search box 506, the subfloor search box 508, the structural member search box 510, the ceiling search box 512 can comprise drop down selection boxes. The drop down selection boxes can be populated by the materials contained with the search engine index 404. The acoustic engine can provide a result of the search in the result indicator 516. If a result is found (e.g., a media file), the media controls 518 can be used to cause playback of the media file. In an aspect, the user can specify one or more inputs for a query into the classification or result search box 502, the floor covering search box 504, the underlayment search box 506, the subfloor search box 508, the structural member search box 510, the ceiling search box 512. For example, the user can specify a floor covering and a classification or result, but not other materials. The query engine 402 can then return a plurality of results made up of media files associated with the specified floor covering and classification or result, but varying in the other materials for the floor/ceiling assembly. In another example, the user can specify a ceiling and a classification or result, but not other materials. The query engine 402 can then return a plurality of results made up of media files associated with the specified ceiling and classification or result, but varying in the other materials for the floor/ceiling assembly. In another example, the user can specify the floor covering and the ceiling, but not the classification or result. The query engine 402 can then return a plurality of results made up of media files associated with the specified floor covering and the ceiling, but varying in the other materials for the floor/ceiling assembly, and display the associated classification or result in the classification or result search box 502.

FIG. 5B is a diagram depicting an example of a web browser screen 501 showing search results generated based on a user defined query. Web browser screen 501 illustrates a user defined query of a classification or result, a floor covering, an underlayment, a subfloor, and a structural member, but not a ceiling. The query engine 402 can then return a plurality of results made up of media files associated with the specified materials and classification or result, but varying in ceiling. The result indicator 516 can display a message indicating that a further selection is necessary in order to cause playback of one of the media files. The user can engage the result indicator 516 to display a list 520 of the various ceiling materials associated with the selected materials “NATURAL IMPACT II PLUS,” “WAFFLE RUBBER,” “PLYWOOD,” “CONCRETE SLAB,” and the classification or result of “58.” Upon selecting a ceiling from the list 520, the user can engage the media controls 518 to cause playback of the associated media file.

FIG. 6 is a block diagram depicting an environment 600 comprising non-limiting examples of a server 202 and a client 206 according to an aspect. The server 202 and the client 206 can be a digital computer that, in terms of hardware architecture, generally includes a processor 602, memory system 604, input/output (I/O) interfaces 608, and network interfaces 610. These components (602, 604, 608, and 610) are communicatively coupled via a local interface 612. The local interface 612 can be, for example but not limited to, one or more buses or other wired or wireless connections, as is known in the art. The local interface 612 can have additional elements, which are omitted for simplicity, such as controllers, buffers (caches), drivers, repeaters, and receivers, to enable communications. Further, the local interface may include address, control, and/or data connections to enable appropriate communications among the aforementioned components.

The processor 602 can be a hardware device for executing software, particularly that stored in memory system 604. The processor 602 can be any custom made or commercially available processor, a central processing unit (CPU), an auxiliary processor among several processors associated with the server 202 and the client 206, a semiconductor-based microprocessor (in the form of a microchip or chip set), or generally any device for executing software instructions. When the server 202 or the client 206 is in operation, the processor 602 can be configured to execute software stored within the memory system 604, to communicate data to and from the memory system 604, and to generally control operations of the server 202 and the client 206 pursuant to the software.

The I/O interfaces 608 can be used to receive user input from and/or for providing system output to one or more devices or components. User input can be provided via, for example, a keyboard and/or a mouse. System output can be provided via a display device and a printer (not shown). I/O interfaces 608 can include, for example, a serial port, a parallel port, a Small Computer System Interface (SCSI), an IR interface, an RF interface, and/or a universal serial bus (USB) interface.
